Patented @11.6.1914,

Be it knownrthat I', Gann C. 'Kus'.mnm, a

- citizen of the United. States,I residing-at Grand Rapids, Michigan, have invented .cer-

tain new and useful Improvements in Concealed Hinges for Coach-Doors, vof which Y the following .is a speeiiication.

This invention relates to 'improvements in concealed hinges for ooach doors. The objects of this invention-are:

- hinge -to accommodate Athe angle and curve and inequalities vof -post and door, also inaccuraciesof construction of the bodies of such vehicles.' I also provide flexibility due to limitedfmovement'on account of oversize of screw holes' of hinge plate accomplishing Vself alineinent of two or -more pintles on sainedoor.

Second, to provlde animproved construetion in which' the. Vhinge is readily detachiso able without, the breaking of fitted joints..` V Third, to provide an improved hinge in which lost motion is obviated when the door is in closed 4osition and the strain relieved on the pin nring the swing of the hinge and when it is in the open position.

Fourth, to `provide a hinge in which the parts of any one are interchangeable with those of any other, .an obvious advantage as this permits the pillar-post-housing to be applied to the casing'in the body department and the hinge meni-ber to the doors in' the door department of a manufactory.

Fifth, to provide a pillarfpost-housing which may be applied reversibly and used on right or-left 'hand -doors at convenience.

Sixth, to provide a pillar-post-housing in combination with the 'pillar of such form that the pillar need be only notched to receive it as distinguished from mortised.

Further objects, and objects relating to details andeconomies of construction will definitely appear from the description to follow.

I accomplish the objects of my invention by the devices and means describedin the following specification.

The invention is clearly defined and pointed out in the claims.

Structurcswhich are preferred embodiments of my invention are fully illustrated in thev accompanying `drawing, .forming a` part of this specification, in which;

Fig. VII is a detail elevation view of one of my hinges in place with the door open, looking toward the pillar plate and illustrating the wedging part 185015 the hinge arm 14. Fig.

VIII is a transverse detail sectional viewv similar to that appearing in Fig. IV, 'of a modified forni and shows detail construction enabling the sheet metal forming the outside surface of the body to be turned inward to avoid raw edge of metal and give a flush finish on the pillar, taken on a line corre-- sponding to line 8*8 of Figs. VII and IX.

Fig. IX is a detail vertical sectional lview through aniodified form, which has preference for certain grades and kinds of bodies wherein the pillar plate 'and housing is of sheet metal stamping, taken on line 9*-9 of Fig. VIII.v Fig. X is a detail'transverse sectional view through the pillar plate and housing, as modified when made entirely of sheet metal, taken on a line corresponding to line 8-8 of Fig. IX. Fig. XI is a detail perspective view of the niodification shown in Fig. X.

In the drawing, similari-numerals of 'refP eience refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the littleA arrows at. the ends of the section lines.

Referring to the numbered parts 'of the drawing, a pillar l is usually finished on the exterior with a plate of aluminum or other metal 2, with a suitable molding 2 around the edge of the same. The door 3 is of any required forni and `is supported liy,f,tli e .'A

hinges. A

A fixed pillar plate 4, having a housing 5,

preferably integral therewith, is let into the pillar by a corresponding notch to receive the hinge arms and is retained inpla'ce-byi` suitable screws, as 6.- A seat 7 is formed on4 y wood, as shown in Fig. V in one construction. Because of the loose fit of .the hinge plate 8, theparts are'etlectively but inconspicuously adjustable to take care of 'ine-'f qualities in the bodies,'particularly when the,

bodies arecurved bodies. The screws are tapped into the pillar plate in another Leonstruction, as appears at 23 in Fig-VI, where the housing 22 is of sheet metal. Each form meets special requirements;

On the detachable hinge plate 8 are hinge arms 16, which extend into the housing 5 and through which4 is disposed the hinge pin 15. The opposite hinge member'12 is let into the door. 3 being secured'by screws 13, and is provided with an outwardly curved hinge arm 14 which extends into the housing, 'and at its outer end, the' pin 15- hinges the same to the arms 16. Owing to thecurvatureof this arm, it'permits the door 3 to `swing outwardly.

The arm 14 1s slightly beveled at 18 and,

- lits with a sliding fit into the aperture 17 outer edge, into which the sheet-like body in the plate 8, so that wl1en 't.he door is swung on its hinges, the hingertits snugly and relievcsstrahi on the hingel pin. The wedgeshaped portion 18 lstrikes the sides f the aperture 17 when the door closes and wedges tight and avoids all play.

Stops 18 are provided and disposed toward the outer side of thehinge plate 8 against which the hinge member 14 strikes to limit the movement ofthesameand prevent the door striking against'lthe outside of the pillar or body.' Wherellthe sheetmetaly exterior 2 is conformed around'the pillar, the structure is modified as clearly appears in Fig. VIII. A longitudinal groove 1s here out in the face of the frame-like plate atits coveringr is extended and secured, the relation fully appearing by considering Fig. XI in this connection. This modified form without the longitudinal groove also appears in Fig. VII, where sheet metal 2 is soldered or welded to the housing wall. In another c onstruction, this pillar plat and housingis formed of astamping 24' having extensions 24', in which the shoulders 11 are eliminated and the plate 8 is screweddirectly tothe seat on the outside of this pillar plate, as clearly appears in Fig. IX. The contour of the stamping appears in cross section in Fig.4 VIII. By shaping the wall thus, the

hinges are interchangeable, .either rights or lefts.

In Figs. x and XI, i Shoa the pinar'- plate and housing entirely of sheet metal,

which may be either a simple stamping, 'or

may' be made with riveted, or soldered, or weldedjoints. I show the same conventionally.- The ends 29 are'extended to'form` the seat forthe'hinge plate. The edges are outyturnedat 29 to form a shoulder and the,l 70

housing 27, corresponding to the housing A -of the main structure, is'extcnded at 28 tolz afford Iacontinums con4 tection to the outer 1 plate 2,' which 1s prererably welded or soldered thereto. From this description, it is clear that the structure can be modiied without departing from myinvention.' The integralconstruction of the pillar plate and housing'i's preferred, but Ihave shown how -thereafter drill the holes for the screws so' that 4the door may thereafter be readily detached without removing.; the pillar lplate from the woodwork and no permanent joint is broken. This -is best accomplished by applying one of a pair of hinges complete and drilling the Screw holes in the seat of the other when placed.

The screw holes are made ,a trifle larger than the screws. This gives a flexibility to the attachment of the hinge', which is -highly desirable, and with the ,loose lit of the hinge plate, assures the most perfect alinement of the hinges which, at the ,same time, are'securely clamped `in place.

Because it is not necessary to break the joint, the material of the body is always protected against moisture and the doors can be readily removedduring the finishing process, or for any other reason, and will, as they tit a me-t-al pillar plate, always go back to place' withoutl perceptible wear.

In Figs. VII, VIII and'IX, I lillustrate the housing 24, corresponding to the housing 5, formed of sheet metal, with extension 24 to form a seat forthe hinge plate, and

lprovide a frame-like plate 26 to receive an Ainset 'hinge plate, 25.- By this means, a shouldered seat is provided lthat is completely adjustable to accommodatethe hinge plate, insuring that when'f-the structure is.

once perfectly adjusted, it can in no way get out ofv line'when it is disassembled and reassembled.

Having thusfdescrib'ed my invention, what I claim as new and desire to secure by Let- 'ters Patent is:
